The valley stands so thick with corn That they do laugh and sing,
but neither verdure nor corn can exist upon the moon, as no plant-life can grow in a vacuum where there is no moisture.
The crater mountains of the moon are its grand peculiarities. We see here that its whole surface has been upturned, convulsed and dislocated with forces of the greatest activity, the results of which remain to this day; so that our rocks are not levelled down by the fury of tempests, nor smoothed by the constant flow of water, as your earthly mountains are, but stand up in all their primitive sharpness. These volcanic craters are of all sizes, from fifty yards to as many miles across, and in the centre of some of them there stand up lofty hills. Now if you could take up your position upon the highest peak of one of these central hills at the time the sun was rising, you would see the tops of the distant mountains forming a circle round you all illuminated by the sun's light; but as there is no atmosphere, there is no twilight, and consequently the great valley immediately beneath your feet would be in the very blackest of darkness.
I know that you and others have often wondered what those dark grey patches are which you can see upon the moon, even with the unassisted eye. Some people call them "The man in the moon, and his bundle of sticks," and the story goes that I went stealing sticks on a Sunday, and for my wickedness was banished (sticks and all) into the moon! Now I most strongly protest against this cruel libel; I never stole any sticks, even on a week-day, much less on a Sunday, and I must say the people must have dreadful weak eyesight, and a dreadfully strong imagination, to see anything in these dark patches that can possibly be stretched into the shape of a man with a bundle of sticks at his back. So I hope you will kindly contradict this calumnious story whenever you can; indeed, in writing, it was partly my object to ask you to do so.
One of the smallest dark markings that you can see on the moon with the naked eye is known to selenographers by the name of Mare Crisium, or the Crisian Sea; its width across from north to south is 280 miles, and its length is 354 miles from east to west, and it contains about 78,000 square miles, more than half as much again as the area of England and Wales--rather a large size for a bundle of sticks, I opine. There are several other dark or grey patches on the moon, some smaller and some larger than the Mare Crisium, but they are all the beds or bottoms of what were once oceans, seas, and lakes, the waters of which have been dried up or evaporated many years ago. Some think they have all gone over to that side of the moon which never turns round towards you, but I can tell you that is not the case; for if any water did exist on the moon's surface, the attraction of the earth would certainly draw it round to that side nearest to you, and so you would be able to see some signs of it, as well as clouds and vapours which would rise from it during the time of full moon.
